UK Centre for Ecology and Hydrology: http://www.ceh.ac.uk/
It provides the most up-to-date available data on river flows, rainfall, soil moisture and groundwater levels from a local to a national scale, with users able to view measurements across the country by clicking on an interactive map and exploring data using a range of graphs.
The portal displays water resources and drought information using a range of data:
– River flows from the National River Flow Archive https://nrfa.ceh.ac.uk/ and Environment Agency https://environment.data.gov.uk/hydrology/index.html (updated daily), Scottish Environment Protection Agency http://sepa.org.uk/, Natural Resources Wales https://naturalresources.wales/?lang=en and the Department for Infrastructure – Rivers https://www.infrastructure-ni.gov.uk/dfi-rivers-overview (updated monthly)
– Rainfall from the Met Office https://www.metoffice.gov.uk/ (provided on a grid, and aggregated up to gauging station catchments and river basins) (updated monthly).
– Soil moisture from UK CEH’s COSMOS-UK soil moisture network https://cosmos.ceh.ac.uk/ (updated daily).
– Groundwater levels from the British Geological Survey https://www.bgs.ac.uk/research/groundwater/datainfo/levels/home.html and UK Measuring Authorities (updated monthly).
